How can I know if a .net event is already handled?

Question

I\'ve written some code to handle an event as follows:

AddHandler myObject.myEvent, AddressOf myFunction

It seemed that everything was work

Answer 1

There's no way to tell that a handler is already attached but you can safely call RemoveHandler on the event before calling AddHandler. If there isn't already a handler, RemoveHandler will have no effect.
